LaserDust MP, LP, XLP



In-Situ laserpölyanalysaattorit  

Our LaserDust monitor is available in three versions, namely Medium Path (MP), Long Path (LP), and Extra Long Path (XLP) to cover stack diameters from 0.5 - 10 m.

LaserDust Monitors use a transmitter / receiver configuration to probe the dust concentration along the optical line-of-sight. Our true non-contact approach (no probes) is superior to point type dust meters. The transmitter is similar for all three versions (MP, LP, XLP), whereas the receivers are of different size.

With innovative laser technology the LaserDust combines two measurement principles in one instrument. At low dust levels it operates with forward scattered light technology: The incident laser light is scattered by dust particles and collected onto a solid-state sensor for dust quantification. This highly sensible mode enables detection limits of < 0.5 mg/Nm3 and is unaffected by dust depositing on the windows. At high dust levels the LaserDust will measure transmittance or opacity: Light absorption by dust particles is captured by a 2nd sensor.
